Dynamic Friction 4002-63180 GeoSpec Coated Drilled and Slotted Disc Brake Rotor

The Dynamic Friction Company (DFC) 4002-63180 is a GeoSpec Coated Drilled and Slotted Disc Brake Rotor engineered to deliver enhanced braking performance and long-lasting corrosion resistance. Featuring DFC's proprietary GeoSpec coating, this rotor forms a durable, attractive silver-gray finish that fights rust far better than conventional paint or zinc coatings — and requires no prep work before installation.

The combination of cross-drilled holes and machined slots works together to maximize braking efficiency. The drilled holes reduce heat buildup on the rotor surface, while the chamfered edges of each hole minimize the risk of cracking under stress. The slots evacuate brake dust, gases, and road debris from the contact surface, preventing pad glazing and improving bite — especially in wet conditions.

Key Features:

• GeoSpec Coating — Patented silver-gray finish provides superior rust and corrosion protection over conventional zinc or paint coatings
• Premium G3000/G11H18 Iron Casting — Engineered for OEM-level strength, stability, and durability
• Cross-Drilled Holes — Chamfered to reduce heat buildup and minimize the potential for cracking
• Machined Slots — Remove brake and road debris, prevent pad glazing, and improve wet-weather stopping distance
• CNC-Machined — Manufactured to the tightest tolerances for precise fitment and consistent performance
• OE Vane Configuration — Matches original equipment vane design for proper and maximum heat dissipation
• 100% Mill-Balanced — Precision cut and electronically balanced for smooth, vibration-free stopping at any speed
• Non-Directional Finish — Promotes faster brake pad bed-in and quieter, smoother stops
• Ships Dry, Ready to Install — No cleaning or additional preparation required before mounting

The DFC 4002-63180 is a direct OE replacement rotor designed to meet the same form, fit, and function as the original equipment part. It is sold as a single rotor unit.
